standards for detailed information about respiratory protection requirements and utilize the services of an Industrial Hygienist or other
Safety and Health Professional to make final decisions about selection of proper respiratory equipment for your workplace or use.
I have read and accept the Terms and Conditions.

INTRODUCTION
This Guide may be used as an aid to select appropriate respiratory protection for
specific contaminants. Because conditions at the worksite can vary substantially, acomprehensive evaluation must be made to determine the correct respiratory protection. When contaminants at a worksite have been identified and concentrations
measured, this Guide may be used to help select the appropriate respirator. Only
qualified professionals, familiar with the actual working conditions and knowledgeable in the benefits and the limitations of respiratory protection equipment, shouldmake the selection. Once a respirator has been selected, it is important to continuallymonitor its effectiveness, as well as the dynamic worksite situation. If selection criteria changes, including but not limited to worksite conditions or standards and regulations, a new evaluation must be made to determine the appropriate
respiratory protection.

*COMPREHENSIVE RESPIRATORY PROTECTION PROGRAM

Wherever respirators are used in a work environment, a comprehensive respiratory
protection program must be implemented in accordance with OSHA 29 CFR 1910.134,
as a minimum. This regulation covers permissible practice, written programs, training, maintenance and care, selection, use, fit testing, cleaning and storage, medical
evaluation, breathing air quality, identification of filters and cartridges, program
evaluation, and record keeping. When a chemical cartridge respirator isused, it can only be used if a cartridge change schedule is developed inaccordance with 29 CFR 1910.134 (d)(3)(III)(B)(2). If a change schedule is notdeveloped you should not use Moldex respirators. See pages 29-31 for more
information.
RESPIRATOR FIT TESTS
Any respirator used by an employee must be fit tested to ensure thatthe respirator is providing adequate protection to the wearer. All Moldex
respirator users should be fit tested to ensure proper fit of the respirator.
OSHA 1910.134 describes the various types of fit tests that may be utilized.

ASSIGNED PROTECTION FACTORS (APF)
All Moldex respirators listed in this Guide are half mask or full face, negative
pressure, air purifying respirators. Generally, these are assigned an APF of 10 or 50
respectively, unless a specific OSHA, Federal, State or Local standard assigns alower APF for a particular class of respirator to be used to protect against a particular substance. In such cases the lower APF must be used. A full facepiece respirator
fitted using a qualitative fit test only receives an APF of 10.
OTHER PERSONAL PROTECTIVE EQUIPMENT (PPE)
Certain chemicals may require other forms of PPE in addition to respirators due toabsorption or damage to the skin, eyes or mucous membranes. When supplying respiratory protective equipment, other PPE must also be considered. Failure to provide
appropriate protection with certain chemicals may result in adverse health effects
and render the use of a respirator ineffective. Lastly, always consider all the hazards
that an employee may be exposed to and the advantages and disadvantages of using
a particular piece of equipment in concert with other items (e.g. hard hats, gloves,
faceshields, etc.).
When using any Moldex respirator, read all applicable warnings and information provided with it. Not all Moldex respirators have been sold with warnings
or use instructions for personnel involved in healthcare or related situations,where there may be the possibility of contact with disease or biological hazards. If you are considering such uses, first call the Moldex Technical Dept., +1(310) 837-6500 ext. 512/550 or +1 (800) 421-0668 ext. 512/550. See additional
warnings in packaging
or Moldex Website or page 4 of this guide.
EXPLANATION OF GUIDE FORMAT
Chemical Names listed are either those used by OSHA in 29 CFR 1910.1000, NIOSH’s
Pocket Guide to Chemical Hazards or ACGIH’s 2021 Guide to Occupational Exposure
Values. Only substances that have OSHA Permissible Exposure Limits (PEL) and/or American Conference of Governmental Industrial Hygienists (ACGIH) Threshold
Limit Values (TLV) are listed in the Moldex suggestions section of this guide, whenappropriate.
CAS Numbers are below the name of most chemicals and are the Chemical
Abstracts Service (CAS) registry number. This number is unique for each chemical.
Synonyms listed are some of those common ‘‘other’’ names of a substance found invarious references, this list is not all inclusive.
Filter Type generally indicates what type of filter and/or cartridge may be considered for protection from a particular substance. Remember these suggestions are
not absolute. Selection must be based on considerationof the work and use situationencountered in a particular environment.
‘‘N’’ means Dusts and Non-Oil Based Mists‘‘R’’ means Dusts, and Oil and Non-Oil Based Mists with time restrictions‘‘P’’ means Dusts and Oil and Non-Oil Based Mists, extended life for Dusts
and Non-Oil Based Mists (see Moldex time restrictions on instructions)‘‘AM’’ means Ammonia/Methylamine**

2‘‘AG’’ means Acid Gas‘‘FORM’’ means Formaldehyde“OV” means Organic Vapor“OV/AG” means Organic Vapor/Acid Gas“MULTI” means Multi Gas/Vapor“95” means 95% efficient“99” means 99% efficient“100” means 99.97% efficient“/” means OR. For example, 8940/8990 means you may use either filter.
“FF” means full face respirator; 9000 is suggested.
*Respirator users outside of the United States must comply with all theirapplicable regulations.
**Any non-water based liquids or mist should be considered oil-based, as wellas particulates that may have absorbed non-water/based component.
Note that combinations of the above may be listed. Also note that combination
Moldex cartridges (7300/8300) may be used where an OV or AG is listed, but theservice life of the cartridge will be considerably less for the particular substance.
A similar situation of reduced service life exists with the 7600/8600 multi-gas
cartridges used against various contaminants, see instructions for specificinformation.
Moldex Suggestions are the Moldex respirators that are appropriate for protection
from the substance listed. For example, remember, anywhere a basic Moldex “N95”is suggested the 2400N95 (2800N95) or 2500N95 (2940R95) may also be used.
The 2400N95 or 2800N95 is usually suggested where protection from dusts
or non-oil based mists is required and nuisance level (below the PEL) organic
vapor odors are also present. The 2500N95 is usually suggested where protection from dusts or non-oil based mists is required and nuisance level (below
the PEL) acid gas irritants are also present and 2940R95 for dusts and both oil
and non-oil based mist.
Additionally, any situation where a particular Moldex product is suggested you may
move to a higher level of protection provided the type of protection is equivalent. For
example,– you may use the 2310N99 in place of the 2200N95 if dust or
non-oil based mist protection is required;– you may use the 7940/8940 in place of the 2310N99 if protection
from a dust, fume or mist is required;– you may use any N99 respirator/filter in place of any N95
respirator/filter.
– you may go from a half mask facepiece respirator to a full facepiece respirator with equivalent or higher filters/cartridges.
BUT– you may not go from 2200N95 to 7100/8100 to protect against
a fume because 7100/8100 is used to protect against organic
vapors only;AND– you may not go from a 7940P100/8940P100 to a 2300N95 to protect against
things such as lead because lead requires an N, R, or P100 filter, or from a
2730N100 to a 2400N95 because the efficiency level is lower.
– you may not go down from a full facepiece to a half mask without proper
evaluation of the workplace.
– Note: Where oil based aerosols are present only an R or P Series
filter may be used. Moldex suggests that you assume that any
non-aqueous liquid is oil-based.
TLV’s and PEL’s are listed where either one or both exist. We suggest that in cases
where both a TLV and PEL exist for a particular substance, that the lower of thetwo be used. You must also check if state and local regulations may be applicable.
An ‘‘o’’ next to exposure limit indicates it is an OSHA PEL. A ‘‘t’’ indicates
it is an ACGIH TLV.
Exposure limit concentrations may be listed as either ppm (parts per million), or mg/
m3 (milligrams per cubic meter),mppcf (million particles per cubic foot) or f/cc
(fibers per cubic centimeter of air).
All exposure limits refer to 8 hours per day, 40 hours per week Time Weighted
Averages (TWA), unless otherwise stated.
If a ‘‘c’’ appears next to a limit this indicates that it is a ceiling value which refers to
the concentration that should not be exceeded at any time during work exposure.
If an ‘‘s’’ appears next to a limit this indicates that it is a short term exposure limit(STEL), which refers to a 15 minute TWA (unless otherwise indicated), which shallnot be exceeded during a workday.

Both ‘‘s’’ and/or ‘‘c” designations may be in addition to or in lieu of anotherexposure limit.

studies do not provide mechanistic evidence of key characteristics ofcarcinogenicity which are sufficient to classify the agent into one of theother categories.

A ‘‘skin’’ designation indicates that the substance can be absorbed through the skin,eyes or mucous membranes and appropriate measures must be taken to avoid
absorption.
A “SEN” indicates TLV-confirmed potential for worker sensitization as a result of
dermal contact and/or inhalation exposure based on the weight of scientificevidence.
A “DSEN” designation indicates that the substance may cause dermal sensitization
resulting from the interaction of the absorbed agent and ultraviolet light (i.e.
photosensitization).
A “RSEN” designation indicates the substance may cause respiratory sensitization.
A “OTO” designation highlights the potential for a chemical to cause hearing impairment alone or in combination with noise, even below 85dBA.
For more specific definitions refer to 29 CFR 1910.1000 and to the
ACGIH TLV Booklet.

TLV-A5: Not Suspected as a Human Carcinogen: The agent is not suspected(t-A5) to be a human carcinogen on the basis of properly conducted epidemiologic
studies in humans. These studies have sufficiently long follow-up, reliable
exposure histories, sufficiently high dose, and adequate statistical power toconclude that exposure to the agent does not convey a significant risk ofcancer to humans; OR, the evidence suggesting a lack of carcinogenicity inexperimental animals is supported by mechanistic data demonstrating alack of the key characteristcs of carcinogenicity.
Substances for which no human or experimental animal carcinogenic data have beenreported are assigned no carcinogen designation.
Exposures to carcinogens must be kept to a minimum. Workers exposed toA1 carcinogens without a TLV should be properly equipped to eliminate to
the fullest extent possible all exposure to the carcinogen. For A1 carcinogens
with a TLV and for A2 and A3 carcinogens, worker exposure by all routes
should be carefully controlled to levels as low as reasonably achievablebelow the TLV.
OSHA designates carcinogens as follows:

IDLH (Immediately Dangerous to Life and Health) and LEL (Lower Explosion
Limit) are levels taken directly from the 2007 NIOSH Pocket Guide to
Chemical Hazards. In cases where the LEL is listed it is considered as IDLH.
In all cases the LEL is listed as 10% LEL to provide a safety factor against
explosion.

CA: Carcinogen defined with no further categorization.
Additionally,– If specific OSHA standards exist for a substance, it is listed
in this section.

N.D. means not determined.
Comments list any additional points that should be noted such as:– If a substance is a carcinogen or a suspected carcinogen, it is listed here.
Note that only when OSHA or ACGIH consider a substancea carcinogen or suspected carcinogen it is listed. Carcinogen orsuspected carcinogen from any other organizations or agencies
have not been included in this Guide.

– If OSHA is in the process of changing the regulation of a particular
substance, it is listed as ‘‘OSHA in the process of 6b rulemaking.’’– If ACGIH intends to change a TLV or a carcinogen designation,
it is listed as ‘‘ACGIH NIC (Notice of Intended Change).”– If ACGIH has a Biological Exposure Indices (BEI), it is listed as‘‘Substance for which an ACGIH BEI exists.’’ Note: ACGIH should be
consulted for further detail when BEI is listed.

ACGIH designates carcinogens as follows:
TLV-A1: Confirmed Human Carcinogen. The agent is carcinogenic to(t-A1) humans based upon the weight of evidence from epidemiologic
studies.

– If ACGIH intends to change a short term exposure limit or ceiling value, it
is listed as ACGIH NIC STEL/CEIL.

TLV-A2: Suspected Human Carcinogen. Human data are accepted as(t-A2) adequate in quality but are conflicting or insufficient to classify theagent as a confirmed human carcinogen; OR, the agent is carcinogenic inexperimental animals at dose(s), by routes(s) of exposure, at site(s), of
histologic type(s), or by mechanism(s) considered relevant to worker
exposure. The A2 is used primarily when there is limited evidence of
carcinogenicity in humans and sufficient evidence of carcinogenicity inexperimental animals is supported by mechanistic evidence of key
characteristics of carcinogens that are relevant to humans.

– If ACGIH has a threshold value - surface limit, the concentration on
workplace surfaces that is not likely to result in adverse effects following
derma exposure or incidental ingestion, it is listed as †-SL.
Pages 32-34 contains names of chemicals that Moldex does not recommend its
respirators to be used against. Refer to this list when you are not able to locate achemical in the Guide as it may be listed there. Moldex does not make suggestions
for chemicals not listed in the Guide.
Short service life means that cartridge will have a low service life.

TLV-A3: Confirmed Animal Carcinogen with Unknown Relevance to Humans:(t-A3) The agent is carcinogenic in experimental animals at a relatively
high dose, by route(s) of administration, at site(s), of histologictype(s), or by mechanism(s) that may not be revelant to worker
exposure. Available epidemiologic studies do not confirm an
increased risk of cancer in exposed humans. Available experimental animal
evidence suggests mechanism(s) and/or dosimetry that the agent is unlikely
to cause cancer in humans except under improbable routes or levels of
exposure.
TLV-A4: Not Classifiable as a Human Carcinogen: Agents which cause(t-A4) concern that they could be carcinogenic for humans, but which can
not be assessed conclusively because of a lack of data. In vitro or animal

These are Warnings and Limitations that all users must be made aware of in addition to all warnings and other information on the outside of the Moldex respirator
packaging or other published related information. You must read and comply with these Warnings and Limitations at all times and if your employer has determinedthat it is appropriate to use this respirator.
Proper use of this respirator may reduce but will not eliminate the risk of illness or death from exposure to some Chemical, Biological, Radiological, or Nuclear(CBRN) hazards. CBRN hazards include, but are not limited to, bacteria, toxins, and viruses that can cause death, serious bodily injury or disfigurement. The long-range
and short-range risks of CBRN hazards and the amount and manner of exposure that may produce such risks remain to a great extent unknown. Use of this respirator
must be in accordance with the Centers for Disease Control (CDC) Health Advisories or any other Local, State or Federal recommendations for use of respirators against
specific CBRN hazards. This respirator should not be used for many CBRN hazards.
There are more efficient models of respirators with a higher level of protection available from Moldex and other manufacturers. It is up to the employer, andnot Moldex, to determine if a respirator should be worn and if so, which type, size, level of protection, and model.
BACKGROUND
The National Institute for Occupational Safety and Health (NIOSH), a branch of the CDC and a U.S. Government agency, is responsible for testing and certifying respirators
for protection against hazardous industrial contaminants. Procedures for selecting and using proper respiratory protection are regulated by various governmental
agencies, such as the Occupational Safety and Health Administration (OSHA).
NIOSH tests and certifies certain respirators for use against chemical warfare agents, biological warfare agents or biohazards and provides advisory information for somebiohazards, but OSHA and other government agencies have not set any exposure standards for these agents or biohazards, in general.
Moldex does not make recommendations for any type of respirator to be used against CBRN hazards for workers or the general public.
You should know that there may be no obvious warnings of the presence or release of CBRN hazards.
WARNINGS FOR ALL USERS• This respirator must only be used for substances having Permissible Exposure Limits (PELs) and only where deemed appropriate by your employer.
• This respirator must be fit tested. If you cannot obtain a proper fit, do not use the respirator and do not enter the risk area.
• This respirator is not for use with beards or other facial hair that prevents direct contact between the face and sealing surface of the respirator.
• Moldex respirators, when properly fitted and used as part of a comprehensive respiratory protection program, may reduce wearer exposure to some airborne
hazards, but not all.
• In the event of a sudden or unexpected CBRN hazard release, you may use this respirator for escape only if you have not been provided with a more
appropriate respirator for this type of situation. Do not remove the mask from the face until you have left the contaminated area.
• Do not reuse or store for reuse or hang around neck unless your employer specifically authorizes reuse. Dispose of respirator as a hazardous waste inaccordance with your employer’s directions.
• Use other personal protective equipment, as directed by your employer. Where appropriate use protective gloves when handling or removing respirator anddispose of respirator and then gloves in accordance with your employer’s directions.
• If CDC or other Local, State or Federal agency issues new or revised guidelines for respirator use against specific hazards, users must strictly comply.
WARNINGS FOR USE OF PARTICULATE RESPIRATORS AGAINST BIOHAZARDSOSHA and CDC have recommended the use of any of the particulate respirators approved under 42CFR84 as a means of providing help in complying with aprogram designed to reduce occupational exposure to biohazards including but not limited to tuberculosis, COVID-19 or other airborne biological hazards.
The level of effectiveness of respiratory protection from biohazards cannot be determined with currently available data. However, proper use of appropriate
Moldex respirators in conjunction with a comprehensive respiratory protection program, including but not limited to fit testing, may reduce, but will not
eliminate, risk of infection.
• Be sure to read the Limitations outlined below and strictly follow all Warnings set forth under the WARNINGS FOR ALL USERS.
• When using any Moldex respirator, filter replacement and/or disposal must be handled in accordance with your Healthcare Facility’s comprehensive
respiratory protection program.
• If disinfectants are used to sanitize reusable facepieces, you must consult with your Healthcare Facility and run tests to ensure the compatibility of any
disinfectant with Moldex reusable facepiece materials. Use of disinfectants could impair the efficiency of the respirator and result in a loss of protection.
LIMITATIONS• Respirators may reduce but do not eliminate wearer exposure to airborne hazards or the risk of contracting any disease or infection. Only use thisrespirator as part of a comprehensive respiratory protection program. You will receive no respiratory protection if this respirator is not properly fitted andworn. Additionally, potentially hazardous particles, including infectious agents, smaller than the particle sizes used in NIOSH certifications are likely toexist in certain environments. Some published data indicates that these smaller particles may not be filtered out as effectively as the particle sizes used
by NIOSH [N Series Count Median Diameter (CMD) 0.075 ± .02µm Geometric Standard Deviation 1.86 (GSD) and R & P Series CMD 0.185 ± .02µm 1.6 (GSD)]
when certifying respirators. It is imperative that you determine the size and potential hazards of the particles that may be present in the environment before
selecting appropriate respiratory protection, and that you refer to CDC guidelines when selecting and using any respirator, particularly in environments
where smaller types of particles, such as those referenced above, may be present.
• If the respirator comes in contact with blood or fluids, including body fluids, leave contaminated area as soon as possible and discard and replace therespirator.
• Moldex respirators must not be used on children.
For further information on use of respirators contact Moldex at +1 (800) 421-0668 or +1 (310) 837-6500 ext. 512, your Employer, or CDC at www.cdc.gov or +1 (800) 311-3435

CHANGEOUT SCHEDULES
OSHA 1910.134(d) requires that the employer implement a change schedule for cartridges based on objective
information or data that will ensure cartridges are changed before the end of their service life (see OSHA1910.134
for complete text). A cartridge’s useful service life is how long it provides adequate protection from harmful
chemicals in the air. The service life of a cartridge depends on many factors, including environmental
conditions, breathing rate, cartridge filtering capacity and the amount of contaminants in the air.
If you know what the chemical is and how much of it you are exposed to, then you are ready to estimate howlong your respirator cartridges will work and apply the safety factor.
You must use some type of objective data to develop a changeout schedule. Options for determining a
cartridge’s service life include:
1. Conducting experimental tests.
2. Using a mathematical model like the “Advisor Genius” or “Breakthrough Software.”
OSHA has on its website other means of calculating breakthrough times for various chemicals. You may also
wish to consider use of this website in developing your changeout schedules. Be advised that actual service life
can vary considerably from those calculated using these models. These models only provide rough estimates.
Some of the data you will need specific to the Moldex cartridges in order to use the models on the OSHA
website are:
• 8100 has an average of 36 grams Organic Vapor Carbon, its height is 1.91 cm, inside diameter is 7.77 cm.
• 8600 has an adsorbing equivalent of 28 grams Organic Vapor Carbon, its height is 2.08 cm, inside diameter is
7.76 cm.
• A change out schedule worksheet is provided.
• 7100 has an average of 42.5 grams Organic Vapor Carbon, its height is 2.18 cm, inside diameter is 7.78 cm.
• 7600 has an absorbing equivalent of 36.0 grams Organic Vapor Carbon, its height is 2.18 cm, inside diameter is
7.78 cm.

CARTRIDGE DETAILSREAD THIS WARNING
These weights were estimated by Assay Technology using methods based on their tests. It issuggested that you use default values provided by OSHA for the other cartridge specific parameters.
Lastly, in order for the OSHA models to be used you may have to provide other pertinent data on thechallenge agent which may be found on the SDS or from the chemical manufacturer. These models
can be found at http://www.osha.gov/SLTC/etools/respiratory/change_schedule.html. They arecalled “Respirator Change Shedules.”Moldex suggests that you use the OSHA models, or other means provided by OSHA. Moldex
always recommends that you utilize the most conservative (shortest) breakthrough times. Moldex
recommends that you use any of the methods only for the contaminants contained in this guide.
For more detailed information on these methods, refer to OSHA’s website at:https://www.osha.gov/SLTC/etools/respiratory/advisor_genius_nrdl/work_categories.html
https://www.osha.gov/SLTC/etools/respiratory/change_schedule_mathmodel.html
